摘要
Considering that the multi-valued (folded) localized excitations may appear in many (2+1)-dimensional soliton equations because some arbitrary functions can be included in the exact solutions, we use some special types of muliti-valued functions to construct folded solitrary waves and foldons in the (2+1)-dimensional Broer-Kaup equation.These folded excitations are invesigated both analytically and graphically in an alternative way.
